- How can I take measurements for a Mattioli ring?

Our rings are well know for their unique and contemporary design. The wearability of a ring can change depending on its design, so we encourage you to go through our size guide recommendations to find the perfect ring that will match your finger size. To ensure you get the most accurate ring size, measure your finger at room temperature.

Measuring while your hands are cold will result in a size too small as your fingers can be up to half a size smaller at this time. When looking for rings with a wider band, it may be necessary to get a size larger than your usual size as they can feel a little snugger than the traditional eternity ring. Your perfect ring should fit comfortably, feeling tight enough that it won’t fall off and is still able to fit over the knuckle when you take it off.
